The 'object oftheinve'ntion is'to provide an oven embodying eioient .means `for evenly andeconomically baking articles which are placed therein. A v To these "ends 'the ynovel 'feature and construction of the oven consists in positioning arow ofre-'pro'o'f blocks alcngtheopposite 1 sides ofthe oven ii'oor, or declr, said blocks being 'placed in 'spaces -between the opposite edgesofthe oven-floor andthe adjacentwalls of the vcasing -of the oven.V Said blocks as Well as theloor Aarenaade 'of fire-,proof materiah such as A'terra Vcotta or clay,'andrlthe saidblocksareprovided with iues, some of which extend entirely through the vblocks and others extend only part way 'through llthe blocks. The purpose of closing the nues 4of some Vof'the vblocks .is to con'nefthe heatedl 2d ainwithin the 'blocks while Vother currents of heated a'ir .are passing ufpthroughv kother blocks.V The blocks which extend above the .ojor ofthe oven being -made of terra cotta or other 'suitablereproof material wil-l not "L25 causethe food inthe baking ,pans to be burned or scorched when the side of the pan is in contact with these blocks. l i v V The invention consists in a baking oven of thecharacter hereinafter setforth `and par,h

fthe drawings,` 5 is the casing of theoven consisting of .a top 6, a rear wall 7 a-front wall 7 a bottom 8 and two side walls 9 and Y 10. These walls and the'bottom of the oven are Lbuilt lin the usual manner landfconsist Y preferablyoifsheet metal plates 1l on the outvside fofqthe casing and s'heetfmetal plates -12 50 on the inside of the casing, while in between the' plates 'lil and 12 i'sinterposed insulating Ymaterial 1130i Vany suitable character. 'Itis evident that'. any suitable material otherjthan sheet metal mightvbe utilized `for the plates 1l fandw12. The ".interiorof the V'casing is provided "with a heat compartment Mfan'd. two ibaking compartments and 16. A door 1 7 opens into .the compartment .lfand 'ajdo'or 18 opens into Vthe compartment 16, these doors being pivotally 'mounted at Vvthe top to the ca singoftheoven.

Y Heat `is suppliedjtothe oven by a 'burner 19-V Any Suteldlfstyleof:burnerend f-e vbe ing used. The Vheatr'ed airy and products of combustion `in the heat'compartmentll pass upwardly .through a, passage 2Q `betweenfthe rear wall? ofthe casing and` ajpartition21lof iire-proofA materiah constituting 'a baie. Passages 20 are `also, provided Vbettveen the sidewallsQfand 10 andthe sides of said partition 2l. Vr'lhe partition '2fl'preferably consists ofa 'plurality of fireiprooff blocks 'orti'lesf21 which jare j'suppo'rted `on T-iron supports 22 extending from ione side "of .the Oven to the" other. i f g The baking compartment 15 islocated immediatelyv above the heatcompartment 12; and consists'of a `d'eclz: or floor 23fformedfof blocks or tiles 23. jof nreproof material, which are supported upon `cross VT .pieces 24 extending'rfrom one side of lthe `'oven to the other. The oppositesides of the 'floor 23 are spaced 4:apart 'from lthe 'sides 9 and lO'of the ovenbyspaces'25and `26 respectively. These spaces `have positioned therein ande'xtendr ingfupwardly above 'the floor`23 a series of hollow .blocks vof lfire-proof material, suchas terracotta. The block's'27each' have a passage 29 extending vertically theren through. The "blocks 28each 'have 'ajve'rtical chamber V3:0 thereinvclosed at its upper end. The blocks 27 Varepreferably constructed with -three vertical flues'therein open v at their Q upper ends. Thel `blo` cl s"'2'8l are preferably Y constructed `with three verticaljchambers-BO therein closed at their upperxendsl. A I

The baking compartment "16 .isV o `rov'idec`l` with a door 31, similar'to th'efloor23, con-V sisting oftlijle's Aor bloclrs32 of vlire-"proof material,` which' vvare "suppertedv rby' `cross T pieces A 33 extending from one side of the oven to the other. The ioor 31 is spaced apart at its opposite sides from the opposite sides 9 and 10 of the oven casing the same as the Hoor 23 is spaced apart from said opposite sides, and the spaces between the opposite sides of the i'loor 31 and the walls of the casing are provided with blocks 34 having vertical passages 35 extending 'therethrough and with vertical blocks 36 having vertical chambers 37 therein which are closed at their upper ends. The blocks 34 and 36 are made of lire-proof material such as terra cotta and are positioned inthe spaces adjacent the opposite sidesof the iioor 31. The blocks 34 having fluespassing vertically therethrough are positioned vertically in alignment with the blocks 28 having closed vertical chambers therein, and the blocks 36 having closed vertical chambers therein are positioned in vertical alignmentY with the blocks 27 having vertical fines extending therethrough.

The air and products of combustion from the heat chamber 14 pass upwardly therefrom through the tlues 29 in the blocks 27 and into the chambers 30,`which are closed at their upper ends, in the blocks 28. As the air passes upwardly through the fines 29, it will fill the chambers 37 on the second floor and will be diverted to pass upwardly through the passages 35 in the blocks 34. After the heated air has passed through the passages 35,A it will pass through the chamber 16 and upwardly through an outlet flue 38 in the top 6 of the oven. The heated air being retained in the chambers 30 of the lower compartment 15 and in the chambers 3,7 of the upper compartment 16 adds to the heatingand efficiency of the two compartments 15 rand 16, and the terra cotta blocks 27 and 28 whichproject .up above the floor 23 and the `terra cotta blocks 34 and 36 which project above the floor of the compartment 16 not only diii'use and radiate heat to their respective compartments, but also prevent the pans inwhich the food to be baked is placed from coming into contact with any metal used in the construction of the inner face of said casing in which event the heated metal would overheat the pans in which the material to be baked is'located and cause the material being baked to be burned yor scorched. y

In lieu ofthe burner 19 a tirebox for coal or wood might bensed,` in which case a suitable smokeY tine lwould be provided to carry the smoke arising Jfrom the combustion of such fuel and the noxious gases arisn ing therefrom through said heating compartment and upwardv through the oven chamber or chambers andthence to the open air so asvto preventthe said smoke and noxious gases from coming into contact with the products placed in the chamber or chambers to be baked. Air surrounding the v the Hoor and said walls, and other blocks of material with vertical chambers closed at their upper ends and ypositioned between 'said first-named blocks. y A 2.
